[0002] Embodiments of the present application relate to the technical field of terminals, and in particular to an electronic assembly and an electronic device. BACKGROUND

[0003] With the continuous development of communication technology, the wireless performance of electronic devices such as mobile phones and computers is attracting more and more attention, and therefore, the application of antenna technology on electronic devices is becoming more and more widespread, and the demand is also increasing.

[0004] Taking a mobile phone as an example, different antenna structures are generally designed at different spatial positions on the mobile phone. Specifically, different resonant antennas can be arranged at different positions in the space of the mobile phone to meet the antenna requirements in different scenarios according to actual scene requirements. In related technologies, when the antenna is arranged in the mobile phone, it is mainly arranged on the shell or the middle frame of the mobile phone. For example, on electronic devices with a metal frame and a glass battery cover ID, the traditional design scheme of the antenna generally forms a multi-section antenna by opening a gap on the metal frame. A feeding point is arranged on the circuit board of the mobile phone, and the feeding point is electrically connected with the antenna to realize the feeding of the antenna.

[0005] However, in the above design scheme, spatial interference is prone to occur between the antenna, the gap between the two adjacent antennas, and the feeding points, which causes adverse effects on the feeding of the antenna. SUMMARY

[0092] In order to realize the communication function of the electronic device, an antenna can be provided on the electronic device to transmit and receive signals through the antenna. The performance level of the antenna of the electronic device in the actual use scenario is directly related to the actual experience of the user. At present, the electronic device mostly applies the industrial design (ID) of metal frame, glass shell.

[0093] Taking a mobile phone as an example, different antenna structures are generally designed at different spatial positions on the mobile phone. Specifically, different resonant antennas can be arranged at different positions in the space of the mobile phone according to actual scene requirements to meet the antenna requirements in different scenes. In the related art, the antenna is mainly arranged on the shell or middle frame of the mobile phone. For example, in the electronic device with a metal frame and a glass battery cover ID, the traditional design scheme of the antenna generally forms a multi-section antenna by opening a gap in the metal frame. A feeding point is arranged on the circuit board of the mobile phone, and the feeding point is electrically connected with the antenna to realize the feeding of the antenna. However, in the above design scheme, the antenna, the gap between the two adjacent antennas, and the feeding points are prone to spatial interference, which causes adverse effects on the feeding of the antenna.

In the electronic assembly, at least two antennas are formed on the metal frame, the circuit board and the electronic device are located on one side of the metal frame, and the metal frame and the circuit board and the electronic device have a gap 100b therebetween. The orthogonal projection of the electronic device on the metal frame covers the first antenna, the gap between the first antenna and the second antenna, and part of the second antenna, and the orthogonal projection of the circuit board on the metal frame covers part of the second antenna. One end of the first extension member is connected with one end of the first antenna close to the second antenna, the other end of the first extension member extends into the gap 100b and is electrically connected with the first feeding point on the circuit board, and the second antenna is electrically connected with the second feeding point on the circuit board. In this way, spatial interference between the antenna, the gap between the two adjacent antennas, and the feeding points can be avoided, thereby avoiding adverse effects on the feeding of the first antenna and the second antenna, and further ensuring the use effect of the user.

[0095] It should be noted that the electronic device provided in this application is applicable to employing any one or more of the following communication technologies, such as Long Term Evolution (LTE) communication technology, Wi-Fi communication technology, 5G communication technology, Sub-6G communication technology, Multi-in Multi-out (MIMO) communication technology, and other future communication technologies. Among them, MIMO communication technology refers to an antenna system that uses multiple antennas at both the transmitting and receiving ends, forming multiple channels between transmission and reception, and has extremely high spectrum utilization efficiency.

[0096] The specific structure of the electronic component and the electronic device having the electronic component will be described in detail below with reference to the accompanying drawings (the following embodiments do not highlight the requirements of the communication network, but only describe the working characteristics of the antenna in the electronic device in terms of frequency).

[0097] This application provides an electronic device 200. Specifically, the electronic device 200 may include at least: a display screen 210, a housing 250, and electronic components, wherein the display screen 210 and the housing 250 are respectively located on both sides of the electronic components. Specifically, refer to... FIG. 3 and FIG. 4 As shown, the electronic component may include at least: a circuit board 230, electronic devices 280, and a metal frame 100, wherein the metal frame 100 has at least one slot 100a to form at least two antennas (e.g., FIG. 5 (The first antenna 110 and the second antenna 120 in the middle).

[0098] In other words, the antenna is a slot antenna formed by creating a slot 100a in the metal frame 100. For example, the slot antenna may include a first part, a second part, and a third part separated by the slot 100a, wherein the spaces between the first part and the second part, between the second part and the third part, and between the third part and the first part may be filled with a non-conductive material.

[0099] In practical applications, the position of the gaps 100a can be changed as needed, and each gap 100a can be filled with a non-conductive material (such as plastic) to ensure the integrity of the metal frame 100 in appearance. By flexibly setting the opening position of the gaps 100a on the metal frame 100, different appearance designs can be achieved while ensuring antenna radiation performance, which is beneficial to improving the product quality of the electronic device 200.

[0100] In addition, such as FIG. 6 As shown, the circuit board 230 and the electronic device 280 are located on one side of the metal frame 100, and there is a gap 100b between the metal frame 100 and the circuit board 230 and the electronic device 280.

[0101] With reference to the drawings FIG. 6 As shown, the at least two antennas can include at least a first antenna 110 and a second antenna 120, wherein a normal projection of the electronic device 280 on the metal frame 100 can cover the first antenna 110, a gap 100a between the first antenna 110 and the second antenna 120, and part of the second antenna 120, and a normal projection of the circuit board 230 on the metal frame 100 can cover part of the second antenna 120.

[0102] In the embodiments of the present application, referring to FIG. 7 As shown, the electronic assembly can further include a first extension 130, wherein one end of the first extension 130 is connected to one end of the first antenna 110 close to the second antenna 120, the other end of the first extension 130 extends into a gap 100b between the metal frame 100 and the circuit board 230 and the electronic device 280, and the other end of the first extension 130 is electrically connected to a first feeding point (not shown in the figure) on the circuit board 230, and the second antenna 120 is electrically connected to a second feeding point (not shown in the figure) on the circuit board 230.

[0103] In the electronic assembly, at least one gap 100a is formed in the metal frame 100, so that at least two antennas are formed on the metal frame 100. Taking the case where the number of antennas is two as an example, a normal projection of the electronic device 280 on the metal frame 100 covers the first antenna 110, a gap 100a between the first antenna 110 and the second antenna 120, and part of the second antenna 120, and a normal projection of the circuit board 230 on the metal frame 100 covers part of the second antenna 120.

[0104] At this time, the second antenna 120 is opposite to the circuit board 230, and the second antenna 120 is electrically connected to the second feeding point on the circuit board 230, and by arranging the first extension 130, one end of the first extension 130 is connected to one end of the first antenna 110 close to the second antenna 120, and the other end of the first extension 130 extends into the gap 100b and is electrically connected to the first feeding point on the circuit board 230, so that spatial interference between the first antenna 110, the second antenna 120, the gap 100a between the first antenna 110 and the second antenna 120, and the first feeding point and the second feeding point on the circuit board 230 can be avoided, thereby avoiding adverse effects on the feeding of the first antenna 110 and the second antenna 120.

[0105] It can be understood that in the embodiments of the present application, the first feeding point and the second feeding point can be metal springs, probes or conductive cables, etc., so that the first antenna 110 and the second antenna 120 can be fed by the metal springs, probes or conductive cables, etc. respectively. It should be noted that the specific forming mode of the first feeding point and the second feeding point is not limited in the embodiments of the present application, and is not limited to the above examples, as long as it can play a feeding connection role.

[0106] In addition, in the embodiments of the present application, the number of the first feeding points corresponding to the first antenna 110 can be one, two, three or more, that is, the first antenna 110 can be fed by one first feeding point, or the first antenna 110 can be fed by two first feeding points at the same time, or the first antenna 110 can be fed by three first feeding points at the same time, or the first antenna 110 can be fed by more first feeding points at the same time, and the embodiments of the present application do not limit this.

[0107] Similarly, the number of the second feeding points corresponding to the second antenna 120 can be one, two, three or more, that is, the second antenna 120 can be fed by one second feeding point, or the second antenna 120 can be fed by two second feeding points at the same time, or the second antenna 120 can be fed by three second feeding points at the same time, or the second antenna 120 can be fed by more second feeding points at the same time, and the embodiments of the present application do not limit this.

[0108] In addition, it can be understood that in some embodiments, the first feeding point and the second feeding point cannot interfere with each other in the setting position on the circuit board 230. For example, the first feeding point and the second feeding point can be arranged in sequence along the outer edge of the circuit board 230.

[0109] In the embodiments of the present application, the side of the second antenna 120 facing the electronic device 280 can have a spacing 130a (see FIG. 13) from the first extending piece 130. FIG. 7

[0110] By having a spacing 130a between the side of the second metal frame 100 facing the electronic device 280 and the first extending piece 130, it can be avoided that the second metal frame 100 and the first extending piece 130 interfere with each other in position, and since the feeding connection between the first antenna 110 and the first feeding point on the circuit board 230 is realized through the first extending piece 130, it can be avoided that the feeding connection between the first antenna 110 and the first feeding point on the circuit board 230 is adversely affected.

[0111] ​In one possible implementation, the distance 130a between the side of the second antenna 120 facing the electronic device 280 and the first extension 130 can be 0.1mm-2mm. For example, the distance 130a between the side of the second antenna 120 facing the electronic device 280 and the first extension 130 can be 0.1mm, 0.5mm, 1mm, 1.5mm or 2mm, etc., and this embodiment does not limit this.

[0112] It should be noted that the numerical values ​​and ranges involved in this application are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0113] It should be noted that, in the embodiments of this application, FIG. 8 for FIG. 6 Cross-sectional view at point AA, FIG. 9 for FIG. 6 Cross-sectional view at point BB. FIG. 10 for FIG. 6 Cross-sectional view at CC, FIG. 11 for FIG. 6 The cross-sectional view at DD. According to FIG. 8 to FIG. 11 It can be seen that at BB is the connection position between the first extension 130 and the first antenna 110, and at CC and DD, there is a gap 130a between the first extension 130 and the second antenna 120.

[0114] Additionally, see FIG. 7 As shown in the embodiment of this application, the metal frame 100 may include a first part 140 and a second part 150, wherein one end of the second part 150 is connected to the first part 140, and the other end of the second part 150 is bent toward the electronic device 280.

[0115] Furthermore, the second part 150 can be offset from the first extension 130 in the first direction L1 (see...). FIG. 12 (as shown), or, the second portion 150 may at least partially overlap with the first extension 130 in the first direction L1 (see...). FIG. 13 As shown in the figure, the first direction L1 can be the thickness direction of the electronic device 200.

[0116] The metal frame 100 includes a first portion 140 and a second portion 150. The second portion 150 of the metal frame 100 and the first extension 130 are offset from each other in the thickness direction of the electronic device 200, or the second portion 150 of the metal frame 100 and the first extension 130 overlap at least partially in the thickness direction of the electronic device 200. Both arrangements can ensure that positional interference between the second metal frame 100 and the first extension 130 is avoided, thereby avoiding adverse effects on the power connection between the first antenna 110 and the first feed point on the circuit board 230.

[0117] like FIG. 7 As shown in the embodiment of this application, the first extension 130 may include: a first extension 131 and a second extension 132 connected to the first extension 131, wherein one end of the first extension 131 is connected to the first antenna 110, the other end of the first extension 131 passes through the gap 100a between the first antenna 110 and the second antenna 120 and is connected to one end of the second extension 132, and the other end of the second extension 132 is electrically connected to the first feed point.

[0118] By designing the first extension 130 to include a first extension 131 and a second extension 132, one end of the first extension 131 is connected to the first antenna 110, the other end of the first extension 131 is connected to one end of the second extension 132, and the other end of the second extension 132 is electrically connected to the first feed point on the circuit board 230, a feed connection between the first antenna 110 and the first feed point on the circuit board 230 can be achieved, so that the first feed point on the circuit board 230 can provide good power to the first antenna 110.

[0119] In one possible implementation, the projection of the first extension 131 perpendicular to the first direction L1 lies within the gap 100a between the first antenna 110 and the second antenna 120, and the projection of the second extension 132 perpendicular to the first direction L1 lies on the second antenna 120. In this way, the first extension 131 and the second extension 132 do not stack in the first direction L1 (i.e., the thickness direction of the electronic device 200), thus not increasing the thickness of the electronic device 200 and saving space within the electronic device 200.

[0120] It should be noted that in this embodiment of the application, the first direction L1 (i.e. the thickness direction of the electronic device 200) is the z direction, and the direction perpendicular to the first direction L1 is the x direction or the y direction.

[0121] In some embodiments, such as FIG. 14 to FIG. 16As shown, the electronic assembly can further include a first electrical connecting member 160, wherein the first extending member 130 can be electrically connected with the first feeding point through the first electrical connecting member 160. Specifically, one end of the first electrical connecting member 160 is connected with the first extending member 130, and the other end of the first electrical connecting member 160 is electrically connected with the first feeding point on the circuit board 230, so as to realize the electrical connection between the first extending member 130 and the first feeding point on the circuit board 230, and further realize the electrical connection between the first antenna 110 and the first feeding point on the circuit board 230, so that the first feeding point on the circuit board 230 can feed the first antenna 110 well.

[0122] Also, in some embodiments, as shown in FIG. 15 and FIG. 16 As shown, the electronic assembly can further include a second electrical connecting member 170, wherein the second antenna 120 can be electrically connected with the second feeding point through the second electrical connecting member 170. Specifically, one end of the second electrical connecting member 170 is connected with the second antenna 120, and the other end of the second electrical connecting member 170 is electrically connected with the second feeding point on the circuit board 230, so as to realize the electrical connection between the second antenna 120 and the second feeding point on the circuit board 230, and further realize the electrical connection between the second antenna 120 and the second feeding point on the circuit board 230, so that the second feeding point on the circuit board 230 can feed the second antenna 120 well.

[0123] In addition, on the basis of the above-mentioned embodiments, the at least two antennas can further include a third antenna (not shown in the figure), and the electronic assembly can further include a second extending member (not shown in the figure). Specifically, the setting mode of the third antenna and the connecting mode of the second extending member can include but are not limited to the following two possible implementation modes:

[0124] One possible implementation mode is that the second antenna 120 is located between the first antenna 110 and the third antenna, one end of the second extending member can be connected with one end of the third antenna facing the second antenna 120, and the other end of the second extending member can extend into the gap 100b between the third antenna and the second antenna 120, and the other end of the second extending member can be electrically connected with a third feeding point (not shown in the figure) on the circuit board 230.

[0125] Since the second antenna 120 is located between the first antenna 110 and the third antenna, by setting the second extending member, one end of the second extending member is connected with one end of the third antenna facing the second antenna 120, and the other end of the second extending member extends into the gap 100b between the third antenna and the second antenna 120 and is electrically connected with the third feeding point on the circuit board 230, so that the third antenna and the third feeding point on the circuit board 230 are electrically connected through the second extending member, and the electrical connection between the third antenna and the third feeding point on the circuit board 230 is realized, so that the third feeding point on the circuit board 230 can feed the third antenna well.

[0126] In a possible implementation, the first antenna 110 is located between the second antenna 120 and the third antenna, one end of the second extension member can be connected to an end of the third antenna facing the first antenna 110, the other end of the second extension member can extend into the gap 100b between the third antenna and the first antenna 110, and the other end of the second extension member can be electrically connected to the third feeding point on the circuit board 230.

[0127] Since the first antenna 110 is located between the second antenna 120 and the third antenna, by arranging the second extension member, one end of the second extension member is connected to an end of the third antenna facing the first antenna 110, the other end of the second extension member extends into the gap 100b between the third antenna and the first antenna 110 and is electrically connected to the third feeding point on the circuit board 230, the third antenna and the third feeding point on the circuit board 230 are electrically connected through the second extension member, that is, the feeding connection between the third antenna and the third feeding point on the circuit board 230 is realized, so that the third feeding point on the circuit board 230 can feed the third antenna well.

[0128] At this time, in the embodiment of the present application, the electronic assembly can further include a third electrical connection member (not shown in the figure), wherein the second extension member is electrically connected to the second feeding point through the third electrical connection member. Specifically, one end of the third electrical connection member can be connected to the second extension member, and the other end of the third electrical connection member can be electrically connected to the third feeding point on the circuit board 230, so as to realize the electrical connection between the second extension member and the third feeding point on the circuit board 230, and further realize the electrical connection between the third antenna and the third feeding point on the circuit board 230, so that the third feeding point on the circuit board 230 can feed the third antenna well.

[0129] It can be understood that, in the embodiment of the present application, the third feeding point can be a metal spring, a probe or a conductive cable, etc., so that the third antenna can be fed through the metal spring, the probe or the conductive cable, etc. It should be noted that the specific forming mode of the third feeding point is not limited in the embodiment of the present application, and is not limited to the above examples, as long as it can play a feeding connection role.

[0130] In addition, in the embodiment of the present application, the number of the third feeding points corresponding to the third antenna can be one, two, three or more, that is, the third antenna can be fed through one third feeding point, or the third antenna can be fed through two third feeding points at the same time, or the third antenna can be fed through three third feeding points at the same time, or the third antenna can be fed through more third feeding points at the same time, and the present application is not limited thereto.

[0131] Additionally, it is understood that in some embodiments, the positions of the first feed point, the second feed point, and the third feed point on the circuit board 230 should not interfere with each other. For example, the first feed point, the second feed point, and the third feed point may be arranged sequentially along the outer edge of the circuit board 230.

[0132] It is understood that, in the embodiments of this application, the number of antennas in the electronic components can be even greater. For example, at least two antennas may also include a fourth antenna, a fifth antenna, and a sixth antenna, etc. In the electronic device 200 provided in the embodiments of this application, by increasing the number of antennas, the antennas in the electronic device 200 can achieve coverage of more antenna modes.

[0133] In addition, it should be noted that the antenna can be a diversity antenna, a WIFI antenna, a Bluetooth antenna, a GPS antenna, a main antenna, or a mid-to-high frequency multiple-input multiple-output (MIMO) antenna, etc.

[0134] like FIG. 8 As shown in the embodiments of this application, the electronic device 200 may further include: a plastic frame 222a, wherein the plastic frame 222a is connected to the metal frame 100 to form a frame 222, and the plastic frame 222a may be located on the side of the metal frame 100 facing the electronic device 280.

[0135] For example, the plastic frame 222a and the metal frame 100 can be connected via non-destructive micromachining technology (NMT). NMT typically involves creating micropores on the metal surface using a treatment agent, followed by injection molding to allow the plastic to enter the micropores. Alternatively, besides this micropore treatment, a physical hole, such as a through hole with a diameter of approximately 0.8 mm, can be created in the metal to allow the plastic to pass through, thus achieving physical plastic extraction. Of course, in other embodiments, the plastic frame 222a and the metal frame 100 can also be connected via other methods, which are not limited in this application.

[0136] Furthermore, it should be noted that in the embodiments of this application, the electronic device 280 can be any device such as a speaker, camera, motor, or Subscriber Identity Module (SIM), and the embodiments of this application do not limit it in this regard.

In the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0139] The terms "first", "second", "third", "fourth" and the like (if any) used in the description and claims of the embodiments of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence.
